In trying the DataFrame Demo, I get “Connection Error. This demo requires internet access”. I can see in the code this is a urllib.error.URLError. I do have internet access – I can fetch the URL mentioned in get_UN_data, either with curl or in the browser (Chrome).
Hi @norvig! Thanks for the bug report.
Looks like the error message we show in that case is not particularly useful — so I just sent out a pull request that should provide more information next time something like this happens. Sorry about that!
That said, I’m really excited you’re trying out Streamlit! Let us know if you hit any other problems or have thoughts on how we could improve the project.
